LIFE-BOAT.

To all whom it may concern:

Be it known that I, ANDREAS B. Annuals- SEN, a subject of the King ofNorway'residing at 7210 Third avenue, Brooklyn, in

the county of Kings and State of New York, have invented certain newanduseful Improvements in Life-Boats, of which the following is aspecification.

This invention relates to that class of boats which are employed forsaving human lives from sinking on wrecked vessels.

Other objects and advantages of the in.

vention will be pointed out in-the detailed description appearinghereinafter.

In order that the invention may be better understood, reference is hadto the accompanying drawing, in which- 7 Figure 1 is a longitudinalsectionof the forward half of the boat. Fig; '2 is a similar view of therear'half thereof, Fig. 3 is a horizontal section on the line 33 ofFig. 1. Fig. 4 is a horizontalsection on the line 4-4 of Fig. 2. Fig. 5is a transverse section on the line 5-5 of Fig. 1. Fig. 6 is a similarFig. 2. I v

In the drawings 10 denotes the hull of the boat, the same having adoublebottom and transverse bulkheads 11, whereby a number of transversewater-ballast compartments 12 are produced in the bottom of the hull. Atthe how and stern of the hull are air-tight compartments 13 and 14,respectively, and in the hull, along both sides thereof, are seats 15,below which are air-tight compartments 16. The compartments 12 areprovided with man-holes which have c'o v ers 17. p

The hull is closed over by a top 18 having side doors 19 through whichthe crew and passengers enter and leave the boat. T he hull and top arebraced by ribs 20 extending around the same on the inside thereof.

In the'forward part Ofthe hull, on the port side, suitably partitionedoff, is located a closet 91 which is flushed by a-pipe 22 extendingtransversely through the forward Specification of Letters Patent.Application filed August 26, 1912. Serial No. 717,080.

compz'nrtment 12,"and openingatits ends through the sides of the hull,below the water line. Each end of this pipe contains a valve 23. i v

The boat is provided with a screw-propeller 24 and a rudder Thepropeller is driven by a manually operated gearing :26 located in theaft part of the hull. The rudder is operated from a steering wheel 27located forward in the hull, from which lines 28 run to the tiller 29. i

- The gearing 26 is also connected to pumps 30 having suction pipes 31extending into a well 32. Suitable means Will be provided fordisconnecting the pumps from thedrive gearing 2o.

The compartments l3 and 14 may be used for holding provisions {ind otherstores, and the compartments 12 carry a ballast of fresh water-"whichWill be replenished hy sea Water when used up. Inorder that this I may.be' conveniently donetliere is provided a pipe 33 extending along thebottom of the hull, on the inside thereof and having branches 34 whichare, connected to the respective valves Oneend of the pipe 33 isconnected to the pipe 22 so that the compartments may be filled with seawater for ballast. The pipe 33 has a valve 36 controlling the flowthereinto from the pipe 22. The

other end of the pipe is connected to the pumps 80 in order that theballast may be cation, by means of branches 38, with the respectivecompartments 12, said branches having valves 39. This pipe leads toa'hand pump 40 for Withdrawing fresh Water from the cou'ipartments.

n. the "how of the boat is located an oil tank 4l from which lead pipes42, the latter opcning through the sides ofthe hull for sprinkling oilon the water. A similar tank 43 and discharge pipes 44 are located atthe stern of the hoat.

The top 18 has ventilators 45 provided with closures 46. The ventilatorsare swivcompartments 12, and contain eled so that they may be turned inany dii rection, and the closures are adapted to be controlled-'simultaneously by" a longitudi-fone of the rods 48 is pivoted at 48 tothebar 47.,an'd another rod 48 is connected to without affecting theoperation-of vthe 010- the closure, whereas another rod 48isslidtweenthe bar 47 and the closures enables the ventilators to be swung aroundas stated sures. The bars 47 are supported by guides 49, and to' one endof said bars is connected an operating lever 49" provided with asuitvable locking device 49 As shown in Figs.

5 and 6 two rows of ventilators are provided. 1 e

In thesides of the top 18 and on the front thereof are port holes 50which show red and green on proper sides so that side lights may beplaced therein. In the top18, at the forward. part thereof is mounted atubular upright 51 which contains properly colored signal lamps 52. Theupright is movable vertically so that it may be lowered into the boatwhen not in use, as shown by dotted lines in Fig. 1.. Through theupright 51 extend two tubes 53 and '54:, respectively, which pass downinto the boat and open through the top of theupright. The tube 53 is forreceiving and conducting sound from the outside when the boat is closedup. The tube 54 leads to a siren or fog born 55. The upright alsocarries a compass (not shown). The top 18 also carries an aft tubularupright 56 for a stern light 57, and in the day time said upright servesas a support for the pole of a flag.

In the bottomof the hull are sounding pipes 58.

All doors and port hole covers will be constructed so as to make awater-tight closure.

The boat also contains hoisting devices 59 which are employed forlaunching purposes. The launching apparatus is shown and claimed in acompanion application.

In the forward part of the hull, on the starboard side is a locker 60.

A boat constructed as herein described is safe in all kinds of weatherand afiords ample and comfortable accommodation for- In rough a largenumber of passengers.

weather, the boat can be entirely closed up.

The various compartments impart stability to the boat, there is nodanger of the boat upsetting, and the interior arrangement, enables theboat to be easily controlled.

The preferred embodiment oi the invention has eenshown, but it will beunderstood that .various changes in the structural details may be madewithout a departure from the spirit and scope of the invention.

. I claim 1. A boat having a hull provided with transverse bottomcompartments for water ballast, a pipe passing through one of thecompartments and opening through I the sides ofthe hull below the waterline, a pipe connected to said pipe, a valve for shutting off andestablishing communication between said pipes, the second-mentioned pithav ing branches extending respectively into the transversecompartments, a valve in each'of said branches, and a pump having itsinlet connected to the second-mentioned pipe.

2. A .boat having a hull provided with, transverse bottom compartmentsfor water in each of said branches, a pump having its.

inlet connected to the second-mentioned pipe, and a second pumpconnected to the compartments for emptying the same.

In testimony whereof I afiix my signature 1n presence of two witnesses.
